1 Background

　　According to the project document requirements of "Demonstration For Fuel Cell Bus Commercialization in China", Beijing and Shanghai will obtain two hydrogen fueling stations to fill the 12 fuel cell buses (6 buses respectively in Beijing and Shanghai) to operate a combined total of 1.6 million km in about four years. It should be indicated that each hydrogen fueling station's capacity is able of filling 10 fuel cell buses.

　　Beijing Public Transportation Corp. and Shanghai Bus Trolley Corp. are the project management companies.

　　2 Input and Output of the Stations

　　2.1 Input of the Stations

　　The quality of the compressed hydrogen as input of the hydrogen fueling stations should be approved by the supplier of fuel cell buses. The hydrogen supply quantity available for each station is not less than 300 kg per day, at a pressure of 1-15MPa.

　　The hydrogen supplier can sign a supply contract with the project management company in the form of submitting a tender independently to supply hydrogen, or can submit a tender together with the hydrogen fueling station provider with the provider committing to supply hydrogen.

　　2.2 Output of the Stations

　　The requirements for station output are described as follows:

　　(1)Two dispensing nozzles should be installed that can dispense hydrogen at a pressure of 25MPa and 35MPa. These dispensers will be keyed to prevent filling at the wrong pressure.

　　(2)Maximum filling time for a fuel cell bus is not over 10 minutes (or the average filling rate of the dispenser is not less than 50 Nm3/min). The time interval between filling two buses is 5 minutes. The hydrogen filling capacity of each station is not less than 300 kg per day.

　　(3)The compressed hydrogen gas dispenser should have good ground-connection facilities and the fueling interface specification of the dispenser should meet the fuel cell buses supplier's requirements (as defined by the California Fuel Cell Partnership: Fueling Interface Specification or other related international codes and standards).

　　(4)The quality of the hydrogen at the dispenser should be the same as that of the input of the station, and it should be approved by the supplier of the fuel cell buses.

　　3 Station Environment Condition

　　3.1 Temperature range -20 to 42℃ ( Beijing and Shanghai)

　　3.2 Altitude less than 100 m ( Beijing and Shanghai)

　　3.3 Maximum humidity 98.5%, Minimum humidity 3～5%(Beijing area)

　　4 Other Requirements

　　(1)The list of all the equipment of the station, including all the appropriate codes and standards should be provided and documented in detail by the station provider. The installation requirements of the station should be also provided. The station should meet all appropriate Chinese codes and standards (provided by the program office), as well as international codes and standards.

　　(2)The hydrogen fueling station should have a complete set of automatic monitoring systems, in order to control of the operation of the equipment, provide safety monitoring, emergency stop, overpressure release,, and alarms for gas leakage, malfunctions, etc.

　　(3)All emissions from the hydrogen fueling station should strictly conform to the national environmental protection standards and local environmental protection standards of Beijing or Shanghai (provided by the Program Office).

　　Attachment 1 Hydrogen source available in Beijing

　　There is a hydrogen generation system using electrolysis available in Beijing with the capacity of 6000 Nm3/day providing hydrogen purity of 99.999% . There is also a set of equipment to compress the hydrogen to 15MPa with the capacity of 5760 Nm3/day, with an additional compressor for a supply of 40MPa with the capacity of 720 Nm3/day, and re 19 storage tanks to store a hydrogen supply at the 15MPa pressure.

　　Attachment 2 Hydrogen source available in Shanghai

　　Shanghai has plentiful hydrogen sources available from the local chemical and metallurgical industries and intends to use them for developing fuel cell vehicles. The current capacity of supplying high purity hydrogen (>99.99%) is >4,000 Nm3/h. There are also facilities for compressing and filling hydrogen with a capacity of 600Nm3/h@15MPa. This supply is not close to the desired location for the fueling station, and tube trailers or some other mechanism will be required to transport hydrogen to the fueling site.
